Mybatis层编写
数据库配置文件 :jdbc.properties
在resources目录下jdbc.properties
这里我还加了Druid连接池的配置
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/db3?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456
jdbc.init=1
jdbc.minIdle=1
jdbc.maxActive=10
MyBatis的核心配置文件 mybatis-config.xml
DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<package name="com.blb.entity"/>
typeAliases>
<mappers>
<mapper class="com.blb.dao.BookMapper">mapper>
mappers>
configuration>
编写数据库对应的实体类
package com.blb.entity;
public class Books {
private int bookID;
private String bookName;
private int bookCounts;
private String detail;
get/set
编写Dao层的 Mapper接口
package com.blb.dao;
import com.blb.entity.Books;
import java.util.List;
public interface BookMapper {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(@Param("id") int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(@Param("id") int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
//通过书名查书籍返回一个Book
Books queryBookByName(@Param("bookName") String bookName);
}
}
编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包
DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.blb.dao.BookMapper">
<insert id="addBook" parameterType="Books">
insert into books(bookName,bookCounts,detail)
values (#{bookName}, #{bookCounts}, #{detail})
insert>
<delete id="deleteBookById" parameterType="int">
delete from books where bookID=#{bookID}
delete>
<update id="updateBook" parameterType="Books">
update books
set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
where bookID = #{bookID}
update>
<select id="queryBookById" resultType="Books">
select * from books
where bookID = #{bookID}
select>
<select id="queryAllBook" resultType="Books">
SELECT * from books
select>
<select id="queryBookByName" resultType="Books">
SELECT * from books where bookName=#{bookName}
select>
mapper>
编写Service层的接口和实现类
BookService 接口
package com.blb.service;
import com.blb.entity.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BookService {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
通过书名查书籍返回一个Book
Books queryBookByName(String bookName);
}
BookServiceImpl实现类
package com.blb.service;
import com.blb.dao.BookMapper;
import com.blb.entity.Books;
import java.util.List;
public class BookServiceImpl implements BookService{
//sevice 掉用dao层
private BookMapper bookMapper;
public BookMapper getBookMapper() {
return bookMapper;
}
public void setBookMapper(BookMapper bookMapper) {
this.bookMapper = bookMapper;
}
@Override
public int addBook(Books book) {
return bookMapper.addBook(book);
}
@Override
public int deleteBookById(int id) {
return bookMapper.deleteBookById(id);
}
@Override
public int updateBook(Books books) {
return bookMapper.updateBook(books);
}
@Override
public Books queryBookById(int id) {
return bookMapper.queryBookById(id);
}
@Override
public List<Books> queryAllBook() {
return bookMapper.queryAllBook();
}
@Override
public Books queryBookByName(String bookName) {
return bookMapper.queryBookByName(bookName);
}
}
Spring层
Spring整合Mybatis的相关的配置文件 spring-dao.xml
1.加载属性配置文件
<context:property-placeholder location="classpath:jdbc.properties">context:property-placeholder>
2.定义数据源
如果需要更换数据源只需要导入依赖，修改class属性值跟property标签。
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
bean>
3.定义SqlSessionFactory
SqlSessionFactory需要注入数据源跟mybatis路径，这样mybatis-config.xml配置的内容才能生效
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis-config.xml" />
bean>
4. 扫描映射器
-
MapperScannerConfigurer会自动扫描指定包下的所有mapper接口，为我们生成mapper接口的实现类并注入到Spring容器中。
-
注入Spring容器中的的命名策略是使用映射器的非大写的非完全限定类名。可以通过注解
@Repository("xx")来修改。 -
MapperScannerConfigurer是需要使用sqlSessionFactory的，但是当只有一个的时候可以省略，如果要显示注入可以使用如下代码注入来注入，注意这里引用上面的
sqlSessionFactory，但是是value的属性值，而不是ref。 -
这是省略了sqlSession的，如果没有省略sqlSession则sqlSessionFactoryBeanName需要改成
sqlSessionTemplateBeanName，并通过value值引入定义的sqlSession。
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.blb.dao"/>
bean>
配置Spring整合MyBatis，数据源使用Druid或者c3p0连接池

spring整合service层
spring-service.xml
1.自动扫描
<context:component-scan base-package="com.blb.service"/>
2.声明式事务
配置声明式事务，注入数据源，需要导入tx的命名空间。
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
bean>
3.事务的注解驱动
注入定义的事务管理器
<tx:annotation-driven transaction-manager="transactionManager"/>
完整版
如果不通过bean标签注入可以在类上使用注解注入
